Abstract (en)

[origin: US5261302A] A quick-change tool holder includes locating means for repeatably locating a cutting unit at a predetermined angular position with respect to a support member. The support member includes an axial bore for receiving a tubular shank on the cutting unit. The tubular shank of the cutting unit includes a keyway having a first locating surface along one side thereof. The clamping mechanism includes a key having a second locating surface along one side thereof. Upon actuation, the clamping mechanism imposes a torque force on the cutting unit to rotate the first locating surface on the cutting unit into abutting relationship with the second locating surface on the key to repeatably locate the cutting unit at a predetermined angular location. The torque force imposed on the cutting unit by the clamping mechanism therefore overcomes any inaccuracies in center-height adjustment attributable to the tolerance between the key and its corresponding keyway.
